ed on. To prevent engine damage, please observe
the following notes about the temperature rang­
es.
Cold ran ge
If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem­
perature yet. Avoid high eng ine speeds, full ac­
celerating and heavy eng ine loads.
Normal range
The engine has reached its operating tempera­
ture once the LEDs up to the center of the gauge
turn on.
If the . indicator light in the instru­
ment cluster d isplay turns on, the coolant tem­
perature is too
high ¢ page 14.
@ Note
-Aux iliary headlights and other accessories in
front of the coo ling-air intake impa ir the
cooling effect of the coolant . This increases
the risk of the engine overheating dur ing
high ou tside temperatures and heavy en­
gine load.

Instrum ent s and ind icat or light s
-The front spoiler also he lps to distribute
cooling air while driving . If the spoiler is
damaged, the cooling effect w ill be im­
paired and the r isk of the engine overheat­
i ng will increase. See an author ized Audi
dealer or authorized Audi Service Fac ility for
ass istance.
Tachometer
The tachometer displays the engine speed in rev­
olutions per minute (RPM) .
You should shift to the next lowest gear when
the speed is below 1,S00 RPM. The beginn ing of
the red zone in the tachometer indicates the maximum permissible engine speed for all gears
once the engine has been broken in and when it is
warmed up to operating temperature. Before
reaching the red zone, yo u should shift into the
next higher gear, choose the Dor S se lector lever
position, or remove your foot from the accelera ­
tor peda l.
@ Note
The needle in the tachometer @ ¢ page 9,
fig. 3
may only be in the red area of the gauge
for a short time or there is a risk of engine
damage.
@ For the sake of the environment
Upshifting early he lps you to save fuel and re ­
duces operating noise.
(D Tips
Applies to: Sa nd RS mode ls
The engine speed is limited when the eng ine
is cold - the full engine output is not availa­
ble. When the engine is at operating temper­
ature, the red area in the tachometer moves
to a highe r RPM range .
Fuel level
The display @ only wo rks when the ignition is
sw itched on. If the fuel level d rops below 2 .6 gal
(10 li ters), a red L ED w ill tur n on and t he
rD indi ­
cator light will turn
on ¢ page 17. The LED
blinks red when the fuel leve l is very low .

-Do not leave valuables unattended in the ve­
hicle . A locked vehicle is not a safe!
- The LED in the driver's door rail blinks when
you lock the vehicle . If the LED lights up for
approximately 30 seconds after locking,
there is a malfunction in the central locking
system. Have the problem corrected by an
authorized Audi dealer or authorized Audi

Key set
Fig . 15 Your vehicle key set
@ Remote control key or convenience key*
The convenience key* is a remote control key with
special
functions ¢ page 29 and¢ page 68.
You can unlock/lock your veh icle w ith the remote
control key . A mechan ical key is integrated in the
remote control
key ¢ page 28.
@ Separate mechanical key
This key is not intended for constant use. It
should only be used in an emergency. Do not
car­
ry it on your key r ing and do not store it in the ve­
hicle .
Replacing a key
If a key is lost, see an authorized Audi dealer or
authorized Audi Service Facility. Have
this key de­
activated . It is important to bring all keys with
you . If a key is lost, you should report it to your
insurance company.
Number of keys
You can check the number of keys assigned to
your veh icle in the Infotainment system. Select:
the
! CAR ! function button> (Car )* Systems con-
Opening and closing
trol button > Service & control > Programmed
keys .
This way, you can make sure that you have
all the keys when purchas ing a used veh icle.
Electronic immobilizer
T he immobilizer prevents unauthorized use of
the ve hicle.
Under certain circumstances, the vehicle may not
be able to start if there is a key from a different
vehicle manufacturer on the key chain.
Data in the master key
When driving, service and ma intenance-relevant
data is cont inuously stored in your remote
con­
trol key . Your A udi se rvice advisor can read out
this data and tell you abo ut the work your vehicle
needs. This applies also to vehicles with a
con­
venience key*.
Personal convenience settings
If two people use one vehicle, it is recommended
that each person always uses "their own" master
key. When the ign ition is turned off o r when the
vehicle is locked, pe rsonal conven ien ce settings
f or the fo llowing systems are stored and
as­
signed to the remote master key.

-Do not hang heavy objects on the coat
hooks, as they could cause personal injury in
a sudden stop.
CD Note
Objects on the rear shelf that rub against the

Roof rack
Applies to: ve hicles w ith roo f rack
Fig . 60 Attac hment poi nts for the roof rack
If luggage or cargo is to be carried on the roof,
you must observe the following:
- Only a specia lly designed roof rack may be used
on your veh icle. These roof racks are the basis
for a complete roof rack system. Additional at­
tachments/carrie r systems are necessary to
transport luggage and sports equipment. We recommend roof racks and attachments from
the Audi Genu ine Accessor ies program.
-When installing the roof rack, make sure that it
is secured only at the designated po ints on the
roof <=>
fig. 60.
- Note the permitted axle load, permitted total
weight, and permitted roof load of you r vehicle
<=> page 254. The roof load is the total of the
weight of the roof rack, the attachments and
the cargo you are car rying. However, you must
also note the permitted load of the carrie r sys­
tem being used.
_& WARNING
-Follow the installation instructions provided
with the roof rack system.
If you do not se­
cure the roof rack system and objects on the
54
roof correctly, they could come loose from
the vehicle and cause an accident .
-Using a roof rack system increases the risk
of an accident, because it changes the vehi­
cle handling characteristics wh ile driving by
shifting the center of grav ity and/or the
in ­
creas ing the surface area exposed to wind.
You may need to adapt your driving sty le
a nd speed to the cur rent cond itions.
CD Note
Make sure that the luggage compartment lid
and the sunroof* do not come into contact
with objects on the roof when they are open .
@ For the sake of the environment
Your vehicle will require more fuel due to the
increased wind resistance . So remove the roof
rack after us ing it.

Climate control system
Description
The climate control system warms, cools and re­ moves humidity from the air in the vehicle interi­
or. It is the most effective when the windows and
sunroof* are closed. If there is a bui ld-up of heat
inside the vehicle, ventilation can he lp to speed
up the cooling process.
I n all heating mode functions, except for defrost,
the blower only switches to a higher speed once
the engine coolant has reached a sufficient tem ­
perature.
Pollutant filt er
The po llutant filter removes poll utants such as
dust and pollen from the a ir .

A WARNING
Poor visibility can lead to accidents.
- For safer driving, keep all windows free of
ice, snow and fog .
- Become familiar as quickly as possible with
the correct use and function of the climate contro l system, especially with the defrost­
ing and defogg ing function.

- When the temperature is below freezing,
only use the windshield washer system after
the windshield has been warmed by the cli­ mate control system . The washer fluid could
freeze on the w indsh ield and impair v isib il i­
ty .
@ Note
-If you suspect that the climate contro l sys­
tem is damaged, switch the system
off to
prevent further damage and have it checked
by an authorized Aud i dea ler or authorized
Audi Serv ice Facility.
- Repa irs to t he Aud i climate control system
require special techn ical know ledge and
special tools. See an aut ho rized Aud i dea le r
or authorized Aud i Serv ice Fac ility .
@) For the sake of the environment
To save fue l, turn off cooling mode by press­
i ng the
IA/Cl button. This will a lso reduce
emissions.
(D Tips
- T o prevent i nterference with t he heat ing
and cooli ng outpu t and to p revent the win­
dows from fogging over, the a ir intake in
front of the windshie ld must be free of ice,
snow or leaves.
- C ondensation from the coo ling system can
drip and form a pudd le o f water under the
vehicle . This is norma l and does not mean
there is a leak.
- Th e energy management system may tem ­
porarily switc h
off certain functions, such as
the seat heating* or rear window defogger.
These systems are ava ilable again as soon
as the energy supply has been restored.
